It is perhaps one of the oldest philosophical thoughts of humanity, but the origin is uncertain. One highly probable origin may be- primitive humans seeking refuge against the rage of natural forces by worshiping the forces, or making sacrifices before the idol of forces- like storms, volcanoes, fires, and predatory/beneficiary creatures. This origin of religions may explain the rise of polytheism in the beginning, then transforming into the monotheistic religions of the current world. According to some estimates, there are roughly 4000+ religions in the world. But in terms of world population percentile, the major religions are- Christian31.50%, Muslim 23.20%, Hindu 13.8%, Buddhist 6.77%, Sikh 0.35%, Jewish 0.22%, Baha'i 0.11%, and other religions 10.95%. There are also non-religious, and atheist populations in the world.

In this section, we will attempt to learn about the major religions, their origin, history, belief system, way-of-life, rituals, and so on.
